The Screw Turbine is a further development of the Screw Pump. Whereas the Screw Pump pumps the water up, in the Screw Turbine the water flows down. The Turbine rotates due to the flow of the water and energy is transferred to the drive unit. The generated energy is transformed by a generator into electricity. A single Screw Turbine can produce up to 500 kW and a number of Screw Turbines can be placed parallel or in series. Project sizes typically vary between 50 and 2000 kW.
The Spaans Babcock Screw Turbine is probably the most efficient technology for low head hydropower sites. Unique is the fish friendliness, long lifetime and minimal operating costs. Spaans Babcock offers grid connected, off-grid and hybrid systems.
Spaans Babcock can offer the full solution, including gates, screens, remote monitoring and control and after-sales and spares supply.
